The aim of this note is to provide a natural extension of Gelfond's constant $e^π$ using a hypergeometric function approach. An extension is also found for the square root of this constant. A few interesting special cases are presented.
The aim of this note is to provide a new identity connected with the Gauss hypergeometric function. This is achieved using results of certain combinatorial identities and a hypergeometric function approach.
The aim of this research paper is to obtain explicit expressions of (i) $ {}_1F_1 \left[\begin{array}{c} α\\ 2α+ i \end{array} ; x \right]. {}_1F_1\left[ \begin{array}{c} β\\ 2β+ j \end{array} ; x \right]$ (ii) ${}_1F_1 \left[ \begin{array}{c} α\\ 2α- i \end{array} ; x \right] . {}_1F_1 \left[ \begin{array}{c} β\\ 2β- j \end{array} ; x \right]$ (iii) ${}_1F_1 \left[ \begin{array}{c} α\\ 2α+ i \end{array} ; x \right] . {}_1F_1 \left[\begin{array}{c} β\\ 2β- j \end{array} ; x \right]$ in the most general form for any $i,j=0,1,2,\ldots$ For $i=j=0$, we recover well known and useful identity due to Bailey. The results are derived with the help of a well known Bailey's formula involving products of generalized hypergeometric series and generalization of Kummer's second transformation formulas available in the literature. A few interesting new as well as known special cases have also been given.
The purpose of this note is to provide an alternative proof of two transformation formulas contiguous to that of Kummer's second transformation for the confluent hypergeometric function ${}_1F_1$ using a differential equation approach.
In this note we state (with minor corrections) and give an alternative proof of a very general hypergeometric transformation formula due to Slater. As an application, we obtain a new hypergeometric transformation formula for a ${}_5F_4(-1)$ series with one pair of parameters differing by unity expressed as a linear combination of two ${}_3F_2(1)$ series.
The aim in this note is to provide a generalization of an interesting entry in Ramanujan's Notebooks that relate sums involving the derivatives of a function Phi(t) evaluated at 0 and 1. The generalization obtained is derived with the help of expressions for the sum of terminating 3F2 hypergeometric functions of argument equal to 2, recently obtained in Kim et al. [Two results for the terminating 3F2(2) with applications, Bull. Korean Math. Soc. 49 (2012) pp. 621{633]. Several special cases are given. In addition we generalize a summation formula to include integral parameter differences.
Expressions for the summation of a new series involving the Laguerre polynomials are obtained in terms of generalized hypergeometric functions. These results provide alternative, and in some cases simpler, expressions to those recently obtained in the literature.
In this short note, we aim to discuss some summations due to Ramanujan, their generalizations and some allied series
